Is there a way to change the Line Color of a line style through Dynamo? The only parameters I get are Design Option Category Type Name Category Family Name I want to change the color :sweat_smile:

I have turned the Python code above into the C# node and added it to archi-lab.net packages for convenience. It works like this now. [image] You can get the node by simply downloading the package from Package Manager. Cheers! -K

Hmm interesting. It seems to be a read only value?

Please post where you have got up to with your dynamo script and associated python code. Also have you looked at the revit sdk for how you set line colours(color in sdk).

import clr clr.AddReference('ProtoGeometry') from Autodesk.DesignScript.Geometry import * # Import ToDSType(bool) extension method clr.AddReference("RevitNodes") import Revit clr.ImportExtensions(Revit.Elements) # Import geometry conversion extension methods clr.ImportExtensions(Revit.GeometryConv…

Not sure it would work. Did you try to create and apply a new line style instead (see Bimorph LineStyle.Create node for instance)

I Haven’t @Yna_Db because the lines are in blocks etc. figured I was better off changing the color rather than creating a new line and swapping it (fix groups issues etc.)

To set a line colour you do not input the colours separately as you have you do it as follows <element>.LineColor=Color(<Red>,<Green>,<Blue>) therefore your 3 lines will become: i.LineColor = color(IN[1][1],IN[1][2],IN[1][3])
